发明名称 PORTABLE GOLF PRACTICE SWING ASSEMBLY
摘要 <p>A portable golf practice swing assembly (10) has a frame assembly (12) with a net (18) secured thereto. The assembly (10) is secured to a golf ball support structure positioned a predetermined distance in front of the net frame assembly (10). It has a golf ball tee (44) upon which is mounted a golf ball (60). Secured to the front end of the ball is a first restraint line (70) whose forward end is connected by safety lines (73) to the frame assembly (10). A second restraint line (62) is connected to the rear of the golf ball and is secured to the frame assembly (12). At least part of the second restraint line is formed of an elastic shock cord. The ball can thus be driven into the net frame assembly and the shock cord will return it to a position adjacent the golf ball tee.</p>
